STOCKTON - A man was shot and killed at an east Stockton park late Friday, authorities said.

The San Joaquin County Sheriff's Office dispatched deputies to East Side Community Park on East Marsh Street about 11:45 p.m. on reports of gunfire and a loud crash. When deputies arrived, they found a Dodge van backed into a tree in a parking lot at the northeast corner of the park, officials said.

Inside the van, deputies found a man in the driver's seat with a single gunshot wound to his upper body, authorities said. Deputies, fire personnel and medics administered aid to the victim, but they were unable to save his life.

Joshua Craig, 27, of Lockeford was pronounced dead at the scene, said Les Garcia, a spokesman for the Sheriff's Office.

Detectives responded to the scene to take over the investigation, but they have little information to work with, Garcia said. Anyone with information is encouraged to contact the Sheriff's Office at (209) 468-4400. Cellphone users can text information to 274637 (CRIMES) by entering the keyword SJSO followed by their tip.
